I'm picking up what sounds like First Responders or something similar.

The last call was to an 18th month year old who stabbed himself in the eye with a coathanger, and sent a couple of crews to check out the situation and report back on weather an ambulance was needed to take him to Moorfields hospital.

Anyone know who/what it is?

The base seems to have the callsign of 800 Control and the other mobile units are just two or three digit numbers.
